This patch adds IPv6 support for RFC5082 Generalized TTL Security Mechanism. Not to users of mapped address; the IPV6 and IPV4 socket options are seperate. The server does have to deal with both IPv4 and IPv6 socket options and the client has to handle the different for each family. On client: int ttl = 255; getaddrinfo(argv[1], argv[2], &hint, &result); for (rp = result; rp != NULL; rp = rp->ai_next) { s = socket(rp->ai_family, rp->ai_socktype, rp->ai_protocol); if (s < 0) continue; if (rp->ai_family == AF_INET) { setsockopt(s, IPPROTO_IP, IP_TTL, &ttl, sizeof(ttl)); } else if (rp->ai_family == AF_INET6) { setsockopt(s, IPPROTO_IPV6, IPV6_UNICAST_HOPS, &ttl, sizeof(ttl))) } if (connect(s, rp->ai_addr, rp->ai_addrlen) == 0) { ... On server: int minttl = 255 - maxhops; getaddrinfo(NULL, port, &hints, &result); for (rp = result; rp != NULL; rp = rp->ai_next) { s = socket(rp->ai_family, rp->ai_socktype, rp->ai_protocol); if (s < 0) continue; if (rp->ai_family == AF_INET6) setsockopt(s, IPPROTO_IPV6, IPV6_MINHOPCOUNT, &minttl, sizeof(minttl)); setsockopt(s, IPPROTO_IP, IP_MINTTL, &minttl, sizeof(minttl)); if (bind(s, rp->ai_addr, rp->ai_addrlen) == 0) break ...

If some skb are queued to our backlog, we are delaying IPI sending at the end of net_rx_action(), increasing latencies. This defeats the queueing, since we want to quickly dispatch packets to the pool of worker cpus, then eventually deeply process our packets. It's better to send IPI before processing our packets in upper layers, from process_backlog(). Change the _and_disable_irq suffix to _and_enable_irq(), since we enable local irq in net_rps_action(), sorry for the confusion.

kill_fasync() uses a central rwlock, candidate for RCU conversion, to avoid cache line ping pongs on SMP. fasync_remove_entry() and fasync_add_entry() can disable IRQS on a short section instead during whole list scan. Use a spinlock per fasync_struct to synchronize kill_fasync_rcu() and fasync_{remove|add}_entry(). This spinlock is IRQ safe, so sock_fasync() doesnt need its own implementation and can use fasync_helper(), to reduce code size and complexity. We can remove __kill_fasync() direct use in net/socket.c, and rename it to kill_fasync_rcu(). Signed-off-by: NEric Dumazet <eric.dumazet@gmail.com> Cc: Paul E.

Commit 6651ffc8 ("ipv6: Fix tcp_v6_send_response transport header setting.") fixed one half of why ipv6 tcp response checksums were invalid, but it's not the whole story. If we're going to use CHECKSUM_PARTIAL for these things (which we are since commit 2e8e18ef "tcp: Set CHECKSUM_UNNECESSARY in tcp_init_nondata_skb"), we can't be setting buff->csum as we always have been here in tcp_v6_send_response. We need to leave it at zero. Kill that line and checksums are good again. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

My recent patch to remove the open-coded checksum sequence in tcp_v6_send_response broke it as we did not set the transport header pointer on the new packet. Actually, there is code there trying to set the transport header properly, but it sets it for the wrong skb ('skb' instead of 'buff').
